Abstract
Field dependent resistivity measurements have been performed for NdCo2 and PrCo2 compounds. The influence of the localized 4f-moments, inter acting with the 3d-matrix, is accentuated by subtracting the resistivi ty of YCo2 from the observed resistivity values. The excess resistivit y Delta rho(=rho(RCo(2))-rho(YCo2)) which is enhanced above T-C by the presence of 4f-atoms is strongly temperature dependent. The results a re discussed in terms of the thermal variation of the number of the Go -enhanced paramagnetic atoms.
